ОН Н,РО,. H2SO + Н,о Procedure Cyclohexanol (10 g) is weighed into a 50 mL round-bottom three-necked flask, while avoiding getting the liquid on the ground-glass joint. To this is added 2.5 mL of 85% phosphoric acid along with two drops of sulfuric acid (again, avoiding getting the liquids on the joint) and a few boiling stones....

PRELAB EXERCISE EXPERIMENT 21 Synthesis of Aspirin (Acetylsalicylic Acid) What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. The procedure calls for cautious addition of water to the reaction mixture while it is still hot. What purpose does the addition of water serve and why should the addition be done while the reaction mixture is hot? Provide an equation for the reaction involved.Using the quantities of salicylic acid and acetic anhydride...

1. Based upon the results obtained in your experiment, formulate a mechanism that will account for all products observed. What rule does the mix follow? 2. One student refluxed the reaction mixture for 20 minutes instead of just distilling over the product as it is formed. The resultant product was approximately 100% 1-methylcyclohexene. Explain why this happened. 3. The GC depicted in Fig. 1 was obtained on analysis of the dehydration of the alcohol below. Interpret the GC data in...

We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...

From problem 9.10 in the book. An initial experiment at an eyeglass manufacturer has produced poly(methyl methacrylate), whose monomer is (used in eyeglasses and hard contact lenses) with a number average molecular weight of 143,000, by carrying out the reaction at 65 °C for 45 minutes. Since the product design group has determined that a molecular weight of 100,000 is satisfactory, how fast can you speed up the production process and still achieve the desired MW? The activation energies for...
